System and method for detecting air permeability of paper diaper

Abstract

The invention discloses a system and method for detecting the air permeability of a paper diaper. The system comprises a closed container, a control center and a urine injection device, wherein the urine injection device is used for injecting urine into the surface of a to-be-tested paper diaper; the paper diaper is upwards and horizontally spread in the closed container to divide the closed container into an upper cavity and a lower cavity which are not communicated with each other; a first constant temperature and humidity module, a first air circulating flow module and a first weighing module are arranged in the upper cavity, and a second constant temperature and humidity module, a second air circulating flow module and a second weighing module are arranged in the lower cavity; and the first constant temperature and humidity module, the second constant temperature and humidity module, the first air circulating flow module and the second air circulating flow module are connected with the control center. According to the system and the method, the quality of air volatilized from the front and rear surfaces of the paper diaper in the use process can be automatically detected, and then the air permeability indexes of the front and rear surfaces of the paper diaper can be measured, thereby guiding the research and development of the paper diaper.

Description

technical field [0001] The invention belongs to the technical field of nursing product detection, and in particular relates to a system and method for detecting air permeability of paper diapers. Background technique [0002] The air permeability of diapers is an important index parameter to measure the quality of diaper products. Under the same environmental conditions, diapers with good air permeability can greatly improve the comfort of babies wearing diapers, and effectively prevent babies from skin allergies and red buttocks. [0003] However, since there is no rigorous gas permeability testing method in the care product industry, let alone an intelligent testing method, purposeful R&D and production cannot be carried out based on the gas permeability index. Contents of the invention [0004] The object of the present invention is to provide a system and method for detecting the air permeability of paper diapers, aiming at the deficiencies of the above-mentioned prior...
